• suppose man pick up x flowers.
  He gives half flowers he had to guard and guard in return gives 1 flower to man.
  so,
  after 1st door remained flowers towards guard=(x/2)+1
  i.e(x+2)/2
  
  after 2nd door remained flowers towards guard=[(x+2)/4]+1
  
  after 3rd door remained flowers towards guard=[(x+6)/8]+1
  i.e.(x+14)/8
  at the end he is left with same number of flowers he has picked.
  so(x+14)/8=x
  8x-x=14
  x=2
  Hence he should pick up 2 flowers.

• Wine Left Formula: Pt=Pi((a-b)/a)^n
  
  x=x((x-x/2)/x)^3
  x=x(x/2)^3
  8=x^3
  x=2
